We recently encountered three cases of the leakage from the connecting portion of sevoflurane vaporizer in Fabius Tiro produced by Drager company, and in one case of those, oxygen saturation decreased. The connecting portion had leakage merely in the contact with the fixture of the monitor, because of the structure easily displaced by an external force. Further, it was difficult to detect the leakage due to the ability to correct the insufficient supply of fresh gas by taking in air. We hope a reform of the connecting portion and an alarm to inform it if the anesthesia machine detects the leakage.
我们最近遇到了三例由德尔格公司生产的Fabius Tiro型七氟烷蒸发器连接部位泄漏的情况，其中一例出现了氧饱和度下降。由于该连接部位的结构容易因外力而移位，仅在与监测仪固定装置接触时出现了泄漏。此外，由于吸入空气可纠正新鲜气体供应不足的能力，很难检测到泄漏。我们希望对连接部位进行改进，并在麻醉机检测到泄漏时发出警报。
